History
The company was founded in 1947 by André Coyne under the name Engineering Consultancy André Coyne et Jean Bellier (ACJB). Early recognition came through projects such as the Tignes Dam (1952) in France and the Bin el Ouidane Dam (1953) in Morocco. Among its significant initial undertakings were the Kariba Dam on the Zambia/Zimbabwe border (1959) and nuclear reactors at the Marcoule Nuclear Site (1954). However, the firm faced challenges following the collapse of the Malpasset Dam in 1954.
After the passing of André Coyne in 1960, ACJB adopted the name Coyne et Bellier in 1962. The company broadened its project portfolio by designing its 100th dam, the Jatiluhur Dam in Indonesia, while also completing major works like Canada’s Daniel-Johnson Dam (1968) and France’s Tour Aurore office tower (1970).
Electrobel acquired a majority stake in 1976. The milestone of constructing its 150th dam was achieved with Algeria’s El Saada Dam (1978). Following Electrobel’s merger with Tractionnel to create Tractebel in 1987, Coyne et Bellier played key roles in projects such as the Tricastin Nuclear Power Plant (1980) and Paris’s Grande Arche (1989). The firm reached its 200th dam with Morocco’s Aoulouz Dam completion in 1990. Subsequent projects encompassed Turkey’s Birecik Dam (2000) as well as Brazil’s Machadinho Hydroelectric Power Plant and Cana Brava Dam.
In 2009, the company was renamed Tractebel Engineering SA but continues to operate under the original Coyne et Bellier name within its parent organization’s hydraulic division.
